Ultraviolet (UV) Radiation
Ultraviolet (UV) radiation is a type of electromagnetic radiation from the sun, which is not visible to the human eye. It is divided into three categories: UVA, UVB, and UVC. UVA can penetrate deep into the skin and contributes to aging, while UVB is responsible for sunburns and can cause skin cancer. UVC is mostly absorbed by the Earth’s atmosphere and doesn’t reach the surface. While UV radiation is essential for producing vitamin D, excessive exposure increases the risk of skin damage and cancer, making sun protection important.
